Whats the rest of your settings for it like QPI PLL etc? I couldn't get it to even boot with 4.4 at 1.330v set in the BIOS. Also hows the SP120's working for you, was looking at getting a set.

maybe it's a noob question but setting 1.300v in the BIOS gives 1.264v maxed in HWiNFO/HWMonitor etc, any reason why or is it just the CPU only using what it needs?

Mine is set to 1.35v in the BIOS, which after vdroop shows up as 1.328v in CPUZ.
Not surprised it won't boot with only 1.33v in BIOS.

My QPI shows the same as yours in CPUZ.

The SP120 (led) are great fans. Shame I can't say the same about the Triton.
Great at cooling, not so good at holding onto its water.

Nah I meant QPI voltages and any other stuff I may have missed. Still messing around now but currently vcore is at 1.44375v in the BIOS with a max of 1.408v registered through hwmonitor and it still isn't stable. made it through a run of cinebench fine netting 978 points but crashed on IBT. going to give realbench a run but i think i've lost the silicone lottery this time.

edit

So after some testing it seems somewhat stable at 4.4 with a high vcore of 1.4625 in the bios. Made it through passmark and a half hour of realbench no problems but crashed on IBT near the end - 8-10 linpacks although at that point it hit 100c so I'd assume that was thermal throttling causing the fail? Highest temp I saw during Passmark/Realbench was about 88c and the load temps seem to be up a little compared to 4.0GHz. Just wondering is this going to be safe with that high vcore? Definitely didnt get the best chip with Kelt hitting 4.4 at 1.35v but temps wise I'd be fine with what I've hit just the considerably high vcore is concerning. I'll list settings next

22x multiplier 200 blck
Turbo/HT on, C3/6/7/etc disabled
QPI 36X
Uncore 16x
CPU Vcore 1.4625V
QPI 1.355V



Gonna test it some more and fire up a few games to see the temps/stability but here's to hoping.

two and a half hours of GTAO and it seems stable, just hoping 1.4625v in the bios/1.424 under load isnt gonna damage anything

 

[triss]

I have 1.455v (cpuz reported) too lazy to reboot and look in windows sorry showing going through my little E5649 (same thing just lower multi's ) been happy like that for over a year and temps are fine on a H50

I found that its not just a matter of pumping up the juice on Vcore when you get past 4GHz. I think I posted in your overclocking thread there a few other settings you might need to tweak "Differential Amplitude", "PLL Voltage" and "Clock Skew" don't know what they will be called on your board, there are loads of info out there.

1.4Vcore is the max you should take these chips for general use I believe.

I cant find the Guide I used get me past 4GHz, but if you take a look around you might find some help out there.

 

[daveyb]

^ Totally forgot about that, checked the settings you posted, had a little fiddle and managed to drop my vcore in the BIOS to 1.41250v which comes out at 1.392V under load. Still on the high side but way better than 1.4625, cheers!

 

[crazyDAJT]

1.392V reportedly in CPUZ is fine. Mine is 1.4 underload. When your 100% stable there is probably a setting to adjust Vcore depending on load it's "offset voltage" on my board. This drops the volts when ideal or under low load only giving the full voltage at high load situations, stability has been fine with this setting for me.

What are temps like.

 

[DragonQ]

You know, I'm not sure I even remembered the Uncore frequency only has to be 1.5x DRAM frequency for Westmere-EP. I have a feeling mine is at least a notch over 2x (as was common with Bloomfield). I'm not even sure my motherboard lets you choose anything below 2x but I may as well have a look.

Idling right now at the high 40s although I do have the heating on full blast, after a few hours of GTAO lastnight I think the highest temp I saw was about 71c. Will do some more testing today and see what it's like, cheers again for the help!

 

[DragonQ]

Sounds pretty high to me. I've never seen my X5650 idle higher than 40, usually low 30s.

 

[daveyb]

That's at a higher OC and Vcore than yours though (plus a 3/4 year old H50 )

 

[M1k3H]

Just bought a 5650 to replace my aging 920 and hopefully give me another year or two of life, before completely overhauling my system.

Hopefully I'll be able to OC to around 4GHz! Can't wait for it to arrive and get started!

 

[DragonQ]

Just crossflashed my P6T Deluxe V2 to the latest P6T WS Pro BIOS. Should be able to turn off TDP throttling now and hopefully get to over 4 GHz. Had to disable the Firewire interface but I've never used that in my life.

EDIT: BIOS flash worked. I currently have the multiplier manually set to 22x in the BIOS and "High TDP Turbo Mode" enabled, which stops the throttling. However, it still jumps to 23x when a single core is loaded, which makes the system unstable. I can't find any way of disabling the 23x multiplier without disabling turbo entirely...and I can't do that unless I set the multiplier to "auto", which means it's locked at 20x.

Any ideas?

as someone who did the exact same step up of 920 to x5650 you'll easily hit 4ghz, infact my 920s settings carried over as soon as i installed the x5650

Can I ask, what is the multiplier range on the x5650, and also, would it not be wise to just put all clocks to defaults prior to installing it?

Idle = 12x
Standard = 20x
Turbo 3-6 cores = 22x
Turbo 1-2 cores = 23x

Hence my dilemma above, my motherboard allows 20x and 22x to be selected in the BIOS but that doesn't stop it clocking to 23x with single-threaded workloads annoyingly!

Hmm, I might have the same issue, since we have almost the same motherboard. I'll check what ranges I can choose when I get home.

could you not just disable turbo boost and leave it clocked at 22x200?

@M1k3H yeah it probably wouldve been a good idea to reset clocks to stock but the 920 oc was just a vcore/pll voltage bump and then the above mentioned multiplier so nothing crazy.

Just to add my 2p as well, for my 920 Turbo Mode is disabled. Although I have not tried it with it on, it was highly recommended at the time to disable any features that messed with frequency/multipliers.

(I left speedstep on though, to allow the cpu to downclock and I had no issues with that)

 

[DragonQ]

I have the multiplier set to 22x. When I do this, the "turbo boost" option disappears so it can't be "disabled". However, it still jumps to 23x when 1-2 cores are loaded.
